nova-compute manager doesn't send the argument "injected_files" to "driver.spawn":
"nova/compute/manager.py"
def rebuild_instance(self, context, instance, orig_image_ref, image_ref,
injected_files, new_pass, orig_sys_metadata=None):
instance.injected_files = injected_files
network_info = self.network_api.get_instance_nw_info(context,
instance)
device_info = self._setup_block_device_mapping(context, instance)
instance = self._instance_update(context,
instance['uuid'],
task_state=task_states.
REBUILD_SPAWNING,
expected_task_state=task_states.
REBUILD_BLOCK_DEVICE_MAPPING)
# pull in new password here since the original password isn't in
# the db
admin_password = new_pass
self.driver.spawn(context, instance, image_meta,
[], admin_password, <--- Here.
self._legacy_nw_info(network_info),
device_info)
The definition for "driver.spawn" is as following:
"nova/virt/libvirt/driver.py"
def spawn(self, context, instance, image_meta, injected_files,
admin_password, network_info=None, block_device_info=None):
The possible fix is as following:
# instance.injected_files = injected_files
...
self.driver.spawn(context, instance, image_meta,
# [], admin_password,
injected_files, admin_password,
self._legacy_nw_info(network_info),
device_info)
This should be a bug, and exists in the Folsom and master branch.
Since we do not store 'inject_files' information into database, which means that we will lose the information after create_instance finished.
